You say: “We believed with Lord Allah and what has been revealed upon us, and what has been revealed upon Ibrahim, Ismael, Ishaaq, Ya’qoob, and their tribes and what was given to Moses and Jesus and what was given to Prophets from their Lord; we don’t discriminate anyone from them and we are submitted wholly to Him.
Verse 3: 84 is also having the same Message. Here the tribes are the twelve tribes mentioned in verse: 7: 160. That is the offspring of the 10 children of Prophet Ya’qoob and 2 children of Prophet Yoosuf. All Prophets came in Islam and they were commanded to follow Adhikr. So the believer will not differentiate between any Prophet or Messenger. It is told in verses 7: 158 and 34: 28 that: “Muhammad is sent to entire mankind as a Messenger”; and it is told in verse 21: 107 that Messenger Muhammad has not been sent except as a Mercy for entire worlds”.
Since today, there is no group of believers anywhere in the world, the odd believer should read Adhikr in the dawn and dusk, and will do the prolonged ‘Prostration of Recitation’ explained in verses 7: 205-206. That is the mode of prayer in this Last era as Lord taught through His Messenger. See explanation 2: 109 and 130.
